Abstract

The invention discloses a preparation method of a nanotube composite wire containing PBC (Poly Butylene carbonate). The technical scheme of the invention is that 1, a formula is prepared from the ingredients in percentage by weight: PBS (Poly Butylene Succinate), the PBC, PHB (Poly Hydroxy Butyrate), a polyolefin ionomer, halloysite nanotubes, a coupling agent, a nucleating agent, a chain extension agent and the like; 2, the preparation method comprises the steps of (1) drying; (2) material weighting; (3) kneading at a high speed; (4) melting and extruding; (5) cooling and tracking; (6) rolling and bundling. According to the preparation method of the nanotube composite wire containing the PBC, disclosed by the invention, a high polymer material which is suitable for 3D (Three-dimensional) printing is prepared by adopting completely degraded biological materials of the PBS and the halloysite nanotubes, and better tensile strength and better flexibility are obtained while lower printing temperature is obtained.

Description

technical field [0001] The invention belongs to a preparation method of nanotube composite wire. Background technique [0002] 3D printing technology can be divided into laser cladding forming technology (LCF), fusion deposition rapid prototyping technology (FDM), selective laser sintering technology (SLS), stereolithography technology (SLA), three-dimensional printing technology (3DP) and so on. FDM is a fast, safe, and cheap rapid prototyping process. It is easy to operate, the cost of equipment used is low, the process is simple, and there are many types of available materials. It is relatively cheap and has a high utilization rate. It is suitable for office environments. At present, the FDM system accounts for about 30% of the installed rapid prototyping systems in the world, and it is the mainstream technology adopted by the popular desktop 3D printers. [0003] In the synthesis process of polybutylene succinate (PBS), due to the high requirements on pressure and vacuu...
